[SCSI] kill scsi host template suspend/resume
With libata converted to use sdev->manage_start_stop for suspend and
resume, sht->suspend/resume() has no user left and low level
suspend/ressume should be taken care of by low level driver's
suspend/resume callbacks (e.g. PCI or PCMCIA driver callbacks). This
patch removes sht->suspend/resume() callbacks.
This change is suggested by Christoph Hellwig.
